Scope of test: (170-960)HLD (17.9-69.5)HRC (19-683)HB (80-1042)HV (30.6-102.6)HS (13.5-101.7)HRB Hardness system: Richter (HL), Brinell (HB), Rockwell B (HRB), Rockwell C (HRC), Vickers (HV), Shore (HS) Indication error: ±0.5%(HLD=800) Repeatability of indication: 0.8%(HLD=800) Display : Industrial grade 128×64 graphic dot matrix OLED LCD Dimensions : 148mm×30mm×30mm Power supply : Rechargeable lithium battery Continuous working time: About 20 hours Working conditions : Operating temperature -10-50℃; Storage temperature: -30℃-60℃; Relative humidity ≤90%;
The instrument meets the following criteria: ——JJG 747-1999 Leeb Hardness Tester ——ASTM A956-06Standard Test Method for Leeb Hardness Testing of Steel
- Directly shows Leeb scale and Rockwell values - Small and portable instrument, integrated design without connecting cables, improves the reliability - OLED display: clear display data under direct sunlight, suitable for all kinds of lighting conditions - Accurate Measurement: High precision of measurement circuit with value error for ±0.5%(HLD=800),repetition rate value for 0.8% - Support for multiple hardness standard: HL、HV、HRC、HRB、HB、HS - Save 270 hardness measurement data, each group including average, hardness standard. - Support ‘Forged Steel’ material. When impact type D device test sample "forged steel" it can be read directly HB values, without manual look-up table. Hardness value is preset upper and lower limit, automatic alarm beyond the scope, convenient for the user batch testing. - Charge as you want. USB charging, compatible with digital product interface
